MATERIAL FOR LAM P-WICKS.

(SPECIFICATION forming part of Letters Patent No. 430,832, dated. June 24, 1890..

Application filed December 21,1889. Serial No. 384,533. (No specimens.)

To all whom it may concern:

Be it known that I, MYRON H. CHAPIN, of New York, in the county and State of New York, have invented a certain new and useful Improvement in Material for Lamp-Wicks,

of which the following is a specification.

My present improvement consists in a wick material made of raw fibrous Substance havin g the oleaginous matter essentially removed and the exterior surfaces formed into a protective skin by applying an adhesive substance to the same and subjecting them to compression, the two protective skins so formed being held or stayed together by means [5 of threads stitched through the wick material or by means of braces extended through the same between the two protective skins.

In the accompanying drawings, Figure 1 is a perspective view of a wick material embodying my improvement. Fig. 2 is a transverse section of the same. Fig. 3 is a central longitudinal section of the same. Fig. 4 is another longitu dinal section of the same, illustrating a modification.

Similar letters of reference designate corresponding parts in all the figures.

In carrying out my improvement I take any suitable raw fibrous substance, preferably raw cotton, and I essentially remove the 0 oleaginous matter therefrom by subjecting the same to the action of an alkaline solution. The material may be carded or combed to render it uniform. There will be applied to the outer surfaces any suitable substance 3 5 as, for instance, a solution of starch and glue or gelatine-for thepurpose of uniting orbindingthe outermost fibers together in such man ner as to form protective skins a a on opposite sides of the substance. The adhesive substance may be applied with a brush or by rollers. WVhen it has been applied, the material may be subjected to compression, so as to aid in forming the protective skins, and this compression may be exerted through the 5 rollers to apply the adhesive substance, if desirable. The material may be made of much greater width than is required for a lamp-wick and subsequently cut into strips of desired widths for lamp-wicks. The substance between the two protective skins will be left soft and comparatively open or loose,

so as to readily take up oil, and because it is so made the protective skins require to be braced, so that they will not move independently of each other in adjusting a lamp-wick comprising them. I therefore run a line or lines of stitching l) lengthwise of the material composing the wick, and preferably about midway between the side edges. This stitching may be done in any suitable manner. It forms a brace between the two protective skins. For a narrow wick one line will suffice; but for a wide wick several will be needed.

In Fig. 4 I have shown braces b, of adhesive substance. These. may be made by passing through the substance, from the outside of one protective skin to the outside of the other, needles severally provided with an eye or slot near the penetrating end and introducing said end of the needles after their passage through the substance into adhesive substance, allowing the latter to fill the eye or slot, so that on the withdrawal of the needles the adhesive substance will be wiped off by the fibers 7 5,

between the two protective skins and will form braces E2, binding these fibers together between the protective skins. In the protective skins I may prick or puncture small holes a to permit of the passage of oil through the same.

By my improvement I produce a very eflicient, extremely simple, and remarkably cheap Wick material.

What I claim as my invention, and desire to secure by Letters Patent, is-= 1. A wick material composed of raw fiber having the oleaginous matter essentially removed, the exterior surfaces coated with adhesive substance and compressed to form protective skins and braces between the protective skins, substantially as specified.

2. A wick material composed of raw fiber having thev oleaginous matter essentially removed, the exterior surfaces coated With adhesive substance and compressed to form protective skins, and braces consisting of threads stitched through the material and extending between the protective skins, substantially provided with holes and braces between the as spgcifiecl. t 1 1 f H) protective skins, substantially as specified.

3. wic ma eria composec 0 raw 1 er T 7 having the oleaginons matter essentially re- M1 RON CHAPIN' 5 moved, the exterior surfaces coated with ad- Witnesses:

hesive substance and compressed to form pro- S. O. EDMONDS, tecrive skins, and having the protective skins O. R. FERGUSON.
